Cov tseem ceeb sib txawv ntawmsiab - zaus Circuit Court boardsthiab cov kab hluav taws xob zoo tib yam nyob hauv cov khoom siv, tsim, txheej txheem, kev ua tau zoo, thiab kev siv cov xwm txheej. High zaus boards yog optimized rau cov teeb liab kis tau tus mob siab tshaj 1GHz, thaum zoo tib yam boards yog haum rau tsawg-frequency scenarios. Qhov txawv tshwj xeeb yog raws li nram no:
1. Qhov sib txawv ntawm cov khoom tseem ceeb
High zaus Circuit Court board: Cov ntaub ntawv uas tsis tshua muaj dielectric tsis tu ncua (Dk) thiab tsis tshua muaj qhov tsis zoo (Df), xws li polytetrafluoroethylene (PTFE), Rogers series cov ntaub ntawv (xws li RO4350B), los yog ceramic ntim PTFE, yog siv los txo cov teeb liab attenuation thiab qeeb.
Ordinary Circuit Board:FR-4(epoxy resin iav fiber ntau) cov khoom siv feem ntau yog siv, uas muaj tus nqi qis tab sis siab dielectric qhov tsis tu ncua thiab tsis zoo, thiab tsim nyog rau qhov tsawg - zaus.
2. Qhov sib txawv ntawm kev tsim thiab kev tsim khoom
High zaus Circuit Court board:
Kev tswj nruj impedance: kev tswj kom meej ntawm kab dav thiab dielectric thickness yuav tsum ua kom tiav impedance txuam (xws li 50 Ω) thiab txo cov teeb liab kev xav.
Kev xaim zoo: siv cov qauv tshwj xeeb xws li cov kab microstrip thiab kab sawb, cov xaim yog ncaj dua thiab qhov sib nrug yog qhov tseeb dua.
Kev kho deg: Tshuaj kub plating los yog nyiaj deposition feem ntau yog siv los txo cov kev cuam tshuam ntawm nto roughness ntawm cov teeb liab.
Ordinary Circuit Board:
Cov kev cai tsim xoob: cov kev cai tswj tsis tshua muaj impedance, kev xaim feem ntau tsom rau kev sib txuas hluav taws xob.
Tus nqi tseem ceeb: Ua kom yooj yim cov txheej txheem thiab siv cov tshuaj tsuag tin lossis OSP rau kev kho saum npoo kom txo tau cov nqi.
3. Qhov txawv ntawm daim ntawv thov scenarios
High zaus Circuit Court board: siv rau kev sib txuas lus wireless (5G / 6G, hauv paus chaw nres tsheb), satellite navigation (GPS), radar systems, siab - ceev digital circuits (PCIe Gen4/5), thiab lwm yam.
Ordinary circuit board: dav siv nyob rau hauv cov neeg siv khoom siv hluav taws xob (TV, xov tooj ntawm tes), khoom siv hauv tsev, tswj kev lag luam, khoom siv hluav taws xob tsheb (tsis yog RF), thiab lwm yam.
4. Kev ua tau zoo thiab cov nqi sib txawv
Kev ua tau zoo: High zaus Circuit Court boards muaj cov teeb liab kev ncaj ncees zoo dua thiab tiv thaiv - cuam tshuam kev ua haujlwm, tab sis tus nqi siab dua; Cov kab hluav taws xob zoo ib yam muaj tus nqi siab- ua tau zoo thiab tsim nyog rau cov xwm txheej tsawg - zaus.
Nqi: Cov khoom siv hluav taws xob ntau zaus (xws liPTFE) thiab cov txheej txheem yog qhov nyuaj, thiab tus nqi yog ob peb zaug ntawm cov khoom siv hluav taws xob zoo tib yam.
Cias muab, yog tias koj tab tom ua GHz theem teeb liab (xws li 5G lossis radar), koj yuav tsum siv lub siab - zaus Circuit Court board; Yog tias nws yog ib qho khoom siv hluav taws xob tsis tu ncua (xws li lub charger lossis TV), lub rooj tsav xwm tsis tu ncua yog kev lag luam ntau dua thiab siv tau. cov
